Abstract : Dredging in Lake Suwa (Nagano Prefecture) commenced in 1969 and is still in progress. The first stage work, which aimed to remove sediment from shallow zones below 2.5 m, was finished in 1980. However, it brought about no remarkable improvement in water quality. These results were not surprising since the dredged area was only a small part of the lake. Therefore, a new project was established in 1981 to dredge the remaining deeper zones. This paper deals with the dredging and management problems of this new project.
